This is the only time I have seen this beauty, & a very rare sight in SAN. Built for United States Army Air Force (USAAF) as 42-108947. USAAF became USAF in 1947. To US Navy as R4D-5 17220. Re-designated C-47H in 1962. To US Army as NC-47H in 1967, based at Fort Huachuca, Arizona. Painted as "0-7220", derived from its former USN serial (no fiscal year assigned).
